ASIAIR is severely crippled in that it does not understand the horizon coordinate system, or even be able to GOTO a specific hour angle of the mount. This makes it impossible to directly GOTO a fixed point relative to your local horizon.
However, you can bring up an LST (Local Sidereal Time) clock (lots of apps on Apple and Android app stores), and just use the equatorial coordinate system. The LST is simply the RA of the Prime Meridian.
For example, set the RA to the LST minus 6 hours, and declination to +0º, and your OTA should point at the western horizon to clear the roof when you GOTO that coordinate.
Set the RA to LST plus 6 hours, with at declination +0º, and your OTA should point to the eastern horizon.
